Given a table showing points on the graph of a function, determine whether or not the rate of change is uniform.
To solve the problem, let's determine whether the rate of change between each pair of consecutive points is consistent:
First, calculate the rate of change between the first and second points, :
.
Next, calculate the rate of change between the second and third points, :
.
Finally, calculate the rate of change between the third and fourth points, :
.
All calculated rates of change are , indicating a constant rate of change.
Therefore, the rate of change is uniform.
Uniform
Look at the graph below and determine whether the function's rate of change is constant or not:
A uniform rate of change means the function increases (or decreases) by the same amount for every equal step in x-values. It's like climbing stairs with equal step heights!
Yes! You must calculate the rate between all consecutive pairs. If even one pair has a different rate, the change is non-uniform.
Then the rate of change is non-uniform! This means the function could be quadratic, exponential, or another non-linear type.
Each x-value increases by 6: (-1→5), (5→11), (11→17), and each y-value increases by 5: (3→8), (8→13), (13→18). So every rate is !
If the rate of change is uniform (constant), the function is linear! Non-uniform rates indicate non-linear functions like parabolas or curves.
